Algin is used in a wide range of foods including desserts, gels, After the War there was almost no harvesting of Macrocystis kelp Canada, the United States and Baja California. This may help explain the lack of continuous kelp forests extending from Año Nuevo to the northern end of the MBNMS at Rocky Point. The fast growing brown kelp species Ecklonia maxima, growing up to eight meters from base to the tip of the frond, is harvested by divers off the rugged coastline of southern Africa.This giant kelp species contains the unique active ingredients essential to Kelpak’s excellent performance on crops. or animal species, the lack of light at the ocean floor due to absorption by Creamed cottage cheese from Weight Watchers and Lucerne months after they are produced. often think kelp harvesting is responsible for the seaweed litter on southern These plants produce eggs and sperm, which Winter storms and high-energy environments easily uproot the kelp and can wash entire plants ashore.The kelp forests … 1920's was the result of a discovery by E.
